Default STi 6 speed tranny

Exactly why won't this fit/work in my '94 L? I really would like to get this for my car, and I even have my supplier.

What can I do to MAKE it fit/work? If it's at all possible, I'd like to upgrade to the 6 speed. Also, how does this compare with a dogbox tranny/gears. I want the most effective, durable tranny that will hold up to the rigors of drag racing and autoxing. The STi tranny is $5,000, is there a different yet better upgrade for the same $$$ for my 5 speed?

Thanks for your feedback.

Mark

The STI 6-speed may be able to hook up to whatever motor you've got in your 94 L.

You've got to realize that there is alot more than just the tranny you've got to buy and the best price I've heard for the whole kit is $8000 delivered. That still leaves installation.

AFAIK the problem with the 6-speed is a longer or wider (or both) tranny housing that won't fit in the tunnel on the MKI Impreza chassis.

All Mk2 Imprezas have been designed with the new tranny shape in mind, but not the MK1s.

This means the changes you'd have to make to get it to fit would me things like "massaging" the tranny tunnel and probably shortening driveshafts and the like.

This isn't rocket science and it certainly isn't new to the world of hot-rodding, but its far from a bolt-on installation and starts to get expensive FAST.

Default STi Transmission

Hell if your going to pay 8000 for an STi tranny, why not wait for the WRX STi to hit america next year. Then you get all the other goodies with it.

If you look at a lot of the MRT trans mods, they are only for the WRX not for the STi. I think in a few years there will be some real good replacement parts for the WRX trans that will make it even stronger than the expensive STi trans. This is just a speculation, but think about it, there is a whole lot more demand for WRX transmission than for the rare STi.

What about the Kaaz replacement parts? Were these just for the RS? If not, I'm sure they will come out with one. Lets face it, there are a lot of people pouring money into these cars and they are becoming very popular. It would be foolish to not work diligently to be the first to strenthen this transmission.

Be patient, these cars are sooooo new. These part should be developed in the next couple of years.

I'm also considering a half or full dogbox tranny as opposed to this STi tranny.

Opinions?

Hey guys, what's this $8000 pricetag for the 6 speed? I can get the 6 speed tranny for the STi Ver VII for $5,000 from a supplier who only deals in new parts...am I missing something?

Youd be missing at least the new (and different) clutch and flywheel. Along with the different shifter. And since no one has actually done this yet that I've seen so far, no one really knows if the drive shaft and front half shafts work either (but they might).

Shifter, is the same
driveshafts, don't know
Clutch and flywheel have been made larger, But if the input shaft will fit our motor/crank the stock or aftermarket WRX should work.
Some one should buy one and check. Brotha G maybe.

Search this forum. There was a guy who posted a site with that 8000 price tag and the site showed every part you need.

If the shifters are the same why do the STi short shifters have different part numbers for the different trannies? There has to be something different (but it may be trivial). Does anyone (Prodrive maybe) actually know how strong these things are? It would not be fun to spend 8000 for an extra broken gear.

Actually you also need the rear ring/pinion also (need to add that) and I am check if you need anything else. As for the shifter, STi lists different short shifter assemblies for either transmission so I assume they are not interchangable.

Yeah, differens shifters!

The 6spd. has the ring you have to pull up to put the car in reverse, just like the 93.5-98 Supra TT.





Get it?

Default tranny prices

o$8000 is for the complete 2002 STi version from what I have been told. Yes, you can get earlier model year trannys for about $5000, but it won't fit the new models.
